* Now let's draw some rectangles.

* Notes about HSV color notation.
* Imagine hue is a "rainbow" of colors, from 0.0 to 1.0.
* 0.0 is red, then you progress to orange, yellow, green, blue, purple, and
* then back to red again. (Not like a real rainbow.) 1.0 is red also.
* HSV colors are easy for HUMANS, while RGB colors are easy for COMPUTERS.
* Quick, what is the RGB for Pink? Brown?
* In HSV, you would think Pink is a low-saturation red at full brightness,
* thus you could say H=0.0, S=0.5, B=1.0; and that's off the top of my head.
* Brown is a low brightness Orange, so H=0.0888, S=1.0, B=0.6; right out of thin air.
* Need a highly contrasting color? Easy in HSV coordinates.
* Just pick the opposite hue, maybe maximize saturation (opposite of other color),
* and maybe also a min or max brightness. Can't easily come up with highly
* contrasting colors in RGB coordinates in RGB space.
* Need to "soften" colors? Take each HSV coordinate, and lower the saturation
* by 10 %.
* Need to "darken" colors? Lower the brightness of each pixel by 10 %.
